HYDRoCARBoN-BURNER.

Applicaton led August '16, 1919. Serial No. 318,006.

To all whom t may concern Be it known thatv I, JAMES A. KEN- woRTHY, acitizen of the United States, residing at Los Angeles, in the county ofLos Angeles and State of California, have invented new and usefulImprovements in Hydrocarbon-Burners, of which the following is aspecification. y

lfy invention relates to liquid fuel burners, and is particularlyadapted to be used in the fire boxes of ordinary cooking stoves or inhot air or water furnaces.

One object of my invention is to provide a novel means for spreading theflame from the burner, in order that the heat units may be evenlydistributed throughout a considerable area, as well as directing aportion of the flame and heat created thereby on the generator andmixing chamber, whereby-l the fuel may be thoroughly and efficientlyvaporized.

Another object of my invention is to provide a means whereby theoverflow and un- ,.consumed portion of the fuel oil may be caught andutilized for heating the generator preliminary to the starting of theburner.

A further object of my invention .is to.

provide a novel form of mixing chamber.

A still further object of my invention is to provide a means whereby theunconsumed portion of the fuel oil remaining in the generator and pipeleading thereto, may be withdrawn therefrom, and stored away for futureuse after the fuel supply to the burner has been shut off, therebyavoiding the waste of said fuel oil by evaporation, as well as avoidingthe danger of unconsumed oil being generated into gas and forming carbonin the burner. ,v

I accomplish the above and other objects which will appear in thefollowing description, by means of the burner illustrated in theaccompanying drawings, in which:

Figure 1 is a vertical section through my complete burner, as it wouldappear when in use.

Fig. 2 is a transverse section taken on the 'line 2-2 of Fig. 1, viewedin the direo- I tion indicatedby the arrows.

Fig. 3 is a section taken on the line 3--3 of Fig. ,1.

Fig. 4 is a section through the burner and generator, showing a modifiedform of mixing chamber and llame spreader applied thereto.

Fig. 5 is a plan view of Fig. 4, parts which 4or furnace.

would s how in the distance being omitted for the sake of clearness.

Referring more specifically to the drawings, 10 designates thegenerator, adapted to be projected into vthe fire box of a stove orfurnace, the front wall of which is illustrated at 11, which comprises atube 12 provided with an upstanding elbow 13 at one end, and'hasthreaded into its opposite end a fuel pipe 14 which is adapted to extendoutwardly to the exterior of the stove The elbow 13 is exteriorly ofrectangular formation as shown in Fig. 3, and has resting on its topsurface the burner head 15, which comprises a plate provided with acentrally disposed perforation 16.

A mixing chamber 17 is adapted to be supported directly above the burnerhead 15, and preferably comprises a tube 18 open at both ends, as at 19and 20, and provided with a downwardly depending centrally disposed boss21, having a rectangular opening 22,'which fits over the elbow 13, andrests upon the burner head 15, and is supported thereon by means of theshoulder 23, formed in the boss 21. An aperture 24v 'the aperture 24 andsupported above said aperture, by means of standardsl 26 and 27 is thellame spreader 28, which comprises a dished shaped annular disk providedwith a plurality of perforations 29.

Arranged in the bore -of the generator 10 is a coil of wire gauze orsimilar material 30, which serves to break up the fuel into minuteparticles and aid in the vaporizing of the same. f

The free end of the pipe 14 is threaded Ainto a T fitting 32 and the endof a piece of pipe 33 is threaded into said fitting opposite the pipe 14and has threaded onto its outwardly extending end the needle valveshown) At right angles to the .pipes 14 and 13 andv between the same, apiece of pipe 41 is threaded into the fitting 32, the opposite end .ofsaid pipe being threaded into the lower portion of a pump 42, said pumpcompris` 34, said 4valve comprising the valve stem lleading from asource of supply (not 'adaptedto receive the needle point 50 of thevalve 51, said valve being adapted to open and close communicationbetween the barrel 43 of the pump and the pipe 41, aS. clearly shown inFig. 2 of the drawings.

Threaded into a boss 54 on the lower surface of the tube 12, is airingfpan 55 arran ed below the generator and adapted to bev lled withoil in order that the generator may be heated preliminary'to' vstartingthe burner.

In Figs. 4 'and 5 I have illustrated a modified form of mixing chamberand dame spreader and deiector, adapted to coperate with the same styleof l tenerator and bur-ner head as illustrated in ig. 1. The mixingchamber 57 comprises a tubular structure' 58 provided with the bottom,59 and the 'aredwall 60 at its top. vThe bottom 59 is provided with aboss 61, similar tothe boss 21 having .an opening adapted to fit overthe burner-head in a similar manner to that illustrated in Fig. 1./ Thebottom 59 is provided with the'aperture 62 adapted to register with theperforation 16 and with a plurality of openings 63, communicating withthe atmosphere. Y

The wall of tube 58 is provided with a pair of oppositely disposedopenings 65, arranged adjacent thebottom 59 adaptedv for `ghe admissionof air into the mixing chamer.

. AThe top rim of the flared'portion of cham-l ber 57 is provided with apluralityv of notches 67 i adapted to receive the 'projections 68 of aspreader plate 69, said spreader plate being of slightly smallerldiameter than. the diameter of the top of chamber 57; thus leaving vanannular passage 70 for the passage of the flame.

In the operation of my burner, the burner head may be provided with legsor supports (not shown) sothat the burner maybe supported in the rangeor furnace inthe desired position. The valve 84 is then opened as shownin Fig.1, to admit the fuel to the generator, the valve 51 leadinl tothe pump being at this time closed. he oil in the firing-pan 455 is thenlighted to heat the generator to vaporize the fuel assing therethrough.-When sutlicient as has been generated a match is applie at the opening25 of the preferred form or the passage 70 insane drawn in throu h theopen ends 19 and 20 of the'mixing c amber 17 by the action Aof the gasand is mixed withfthe vaporized fuel.

valve' 34,'a certain amount of the ungenerated oil remains inthegenerator and When the' burner 1s shut oli" by closing the i pipes 14and 41, which would become wastedf and befoul the burnerand emitanoifensive odor. In order to conserve this oil andv prevent the odortherefrom, the valve seat` 49 is then opened and the' piston 44drawnupwardly, thus sucking all of the. surplus. oil up into the pump barreland holdingl it there to 'be used in'rechargingthe generator when it isagain desired to start' the burner.

In the modified form as illustrated in Fig.

4, the air enters the chamber 58 where it 1s mixe`d-with the gas issuingfrom the burner tip 16, the flame impinging against `the .plate 69,:isforced downwardly through. the

apertures 63 onto the generator, a portion of the flame passing throughthe annular passage 70 is spread into a large circular flame.

What I claim is: e e p 1. A gas generator construction, comprising agenerator having a source of fuelsupplyleading thereto, means forcontrolling said fuel supply, and a suction mecha? nism interposedbetween said vgeneratorand fuel controlling means,whereby the unconsumedoil may be withdrawn from said generator.

2. A gas generator construction, comprising a generator having a fuelsupply pipe leading thereto, a valve for controlling the supply of fuelthrough said pipe to said generator, 4a pump interposed between saidgenerator and supply controlling valve, anda second valve adapted toopen and close connection bet'ween said first mentioned valve and saidgenerator..

In witness that I claim the foregoing I have hereunto subscribed my namethis 7th p dayl of August, 1919.
